The division of the human family into its two distinct political branches occurred some 10,000 years ago, when humans coexisted as members of small bands of nomadic hunter/gatherers.

The pivotal event of societal evolution was the invention of beer. This epochal event was both the foundation of modern civilization and the occasion of the bifurcation of humanity into its two distinct subgroups: Liberals and Conservatives.

Once beer was discovered, it required grain, and that was the beginning of agriculture. Neither the glass bottle nor aluminum can were invented yet, so it was necessary to stick close to the brewery. That's why villages were formed.

Some men spent their days killing animals to barbecue at night while they were drinking beer. This was the beginning of the conservative movement.

Other men who were weaker and less skilled at hunting, learned to live with the conservatives by showing up for the nightly barbecues and doing the sewing, fetching and hair dressing. This was the beginning of the liberal movement. An interesting evolutionary side note: some of these early liberal men eventually evolved into women.

Liberal achievements include the domestication of cats, the trade union, the invention of group therapy and group hugs, and the concept of democratic voting to decide how to divide the meat and beer that the conservatives provided.

Over the years, conservatives became to be symbolized by the largest, most powerful land animal on earth. Liberals became symbolized by the jackass.

Modern liberals like imported beer (with lime added), but most prefer white wine or imported bottled water. They eat raw fish but like their beef well done. Sushi, tofu, and French food are standard liberal fare. Another interesting evolutionary side note about liberals: most of their women have higher testosterone levels than their men.

Most social workers, personal injury attorneys, journalists, dreamers in Hollywood and group therapists are liberals. Liberals invented the American League's designated hitter rule because it wasn't "fair" to make the pitcher also bat.

Conservatives drink domestic beer, eat red meat, and still provide for their women. Conservatives are big-game hunters, rodeo cowboys, lumberjacks, construction workers, medical doctors, police officers, corporate executives, soldiers, athletes, and generally anyone who works productively outside of government. Conservatives who own companies hire other conservatives who want to work for a living.

Liberals produce little or nothing. They like to "govern" the producers and decide what to do with the production. Liberals believe Europeans are more enlightened than Americans. That is why most of the liberals remained in Europe when conservatives were coming to America. They crept in after the wild west was tamed and they created an art form of trying to get more for nothing.
